Gender-based sex change – the latest developments by scientists from the USA

Изменение пола на генном уровне - новейшие разработки ученых из США A group of scientists from the United States have made a real breakthrough in genetic engineering. During a long search, a unique gene was discovered in the DNA of scarab beetles, the effect on which changes the sex of the embryo. Gender-based sex change – the latest developments by scientists from the USA During research it was found that the sexual development of insects at the stage of embryo formation is controlled by a specific DNA region, DSX. Biologists have identified it for a relatively long time, but only in recent years it has been possible to establish that this gene directly affects a thousand other parts of the male genetic code and more than 250 in females. Indiana University employee Chris Leddon-Retting, who participated in the research, explains that DSX is fundamentally important for the formation of male and female sexual characteristics. It is he who is responsible for ensuring that male insects do not appear in female insects. In fact, this gene controls the functioning of the body of scarabs throughout their lives, activating and suppressing certain sections of the gene code. Disabling this section of DNA leads to very interesting results. For example, sacred lepidopterans of both sexes grew horns (albeit of medium size) during the experiment, although this trait is characteristic exclusively of males, and some individuals even have paired sexual characteristics. Thus, the modification of DSX at the stage of embryo formation allows the sex of an adult to be formed by “remaking” the male into a female.

The gene can be present in most animals, birds, and even humans. That is why American scientists plan to subject homo sapiens to similar tests.
